It was written in Delphi's, as it is easier than C#.I'm using libusbdotcom in my C# projects ( VS2010 ), but since it needs .NET Framework 4 for running the application, I decided to wrote in Delphi.I didn't intend to share the Delphi's full source code, sorry for that, but I'll try to answer your question about it if you really need it.
